BARBED WIRE.

Patented Oct. 28, 1919.

Application filed Novemher 1, 1918. Serial No. 260,662.

To all whom it may concern .Be it known that I, EDWARD I. BRADDooK, acitizen of the United States, residing in "Winchestenin the county ofMiddlesex and State of Massachusetts, have invented an Improvement inBarbed Wire, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to barbed wire and has for its object to providea superior barbed wire at a minimum expense.

To this end, I employ a single wire, strand or rod upon which aremounted a plurality of wires which are interconnected to form a barbedunit having a plurality of barbs extended at an angle to one another andhaving a fixed or permanent relation to one another.

The barbed unit is composed of two substantially short wires which arepassed about the continuous or longitudinal wire so that their armsformed by bending the short wires about the continuous wire extend at anangle to each other and preferably substantially at right angles to eachother, and an arm of one wire is bent about an arm of the other wire tointerlock them and form a unit, in which the arms constituting the barbsare maintained in fixed or permanent relation to one anotherirrespective of the relation of the unit to the continuous orlongitudinal wire and have the unbent arms substantially parallel andextended in opposite directions on opposite sides of a plane through theaxial center of the longitudinal wire, and have the bent armssubstantially parallel to each other and extended in opposite directionson opposite sides of a plane through the axial center of thelongitudinal wire and substantially at right angles to thefirst-mentioned plane.

The continuous wire may be provided with collars or other means forlimiting movement of the barbed units lengthwise of the continuous wire.

. The particular features of the invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a side elevation of a portion of a barbed wire embodyingthis invention.

that their adjacent arms ex Fig. 2, a section on the line 2-2, Fig. 1.

Figs. 3, 4 and 5, details to illustrate the relation of the barbed wiresbefore they are 'tudinal wire, rod or strand, and b, c, the

cross wires which are mounted on the wire a and are interconnected toform therewith the barbed wire unit shown in Figs. 1 and 2.

The cross wire I) is bent around the longitudinal wire a. to encirclethe same and form arms 10, 12, (see Fig. 3) extended preferably at rightangles to each other, and the cross wire 0 is bent about thelongitudinal wire a to encircle the same and form arms 13, 14, (see Fig.4) which extend preferably at right angles to each other, and the crosswires 6, 0 are preferabl arranged so i end substantially' at rightangles to each other as shown in Fig. 5. After the cross wires 7), 0have been arranged as represented in Fig. 5, they are interconnected orinterlocked so as to form a unit, which is eflected by bending an arm ofeach cross wire around an arm of the other cross wire.

As represented in Figs. 1 and 2, the arm 13 of the cross wire 0 is bentaround the arm 10 of cross wire I) and has its free end extendedsubstantially at right angles to the arm 10, while the arm 12 of crosswire I) is bent around the arm 14. of cross wire 0 and has its free endextended substantially at right angles to the arm let, and in theopposite direction to the arm 13.

In this manner the cross wires are interlocked so as to form a barbedunit in which i the barbs have a fixed or permanent relation to oneanother even though the unit be free to turn on the continuous wire aand that the unit is provided with two pairs of substantially parallelbarbs with the barbs of one pair arranged substantially at right anglesto the barbs of the other pair.

Provision is made for preventing or limiting movement of the barbedunits lengthwise on the continuous wire or rod a which may beaccomplished in various ways and in the present instance, this isaccomplished by providing the Wire a with a collar 20 for each unit onthe opposite sides of which the cross Wires are located.

Claims.

1. A barbed ire comprising a longitu dinal Wire or rod, cross Wirescoiled about the said Wire or rod to encircle the same and form arms,with an arm of one cross Wire bent about an arm of the othercross Wireto interlock them and form a unit in Which the unbent arms aresubstantially parallel and extended in opposite directions on oppositesides of a plane through the axial center of the longitudinal Wire andthe bent arms are substantially parallel and are extended in oppositedirections on 013- posite sides of a plane through the axial center ofthe longitudinal Wire or rodand substantially at right angles to thefirst-mentioned plane.

2. A barbed Wire comprising a longitudinal Wire or rod and cross wireslooped name I to this specification.

directions across the longitudinal axis of said Wire or rod fromopposite sides of the latter and substantially at right angles to saidparallel arms and substantially parallel Witheach other.

3. Abarbed ire comprising a longitudinal Wire or rod having a collar,cross Wires passed about the longitudinal Wire on opposite sides of saidcollarto form arms and having an armof one cross Wire bent about an armof the other cross Wire to interlock said cross ires and form a unitWhose armshavea fixed relation to one another.
